KNUT LUDWIG STENDAHL, OFJ BRIDGEPORT,

CONNECTICUT, AS'SIGNOR TO THE HURWOOD MANUFACTURING COMPANY, INCORPORATED, OF BRIDGEPORT, CONNECTICUT, A CORPO- RATION OF CONNECTICUT.

To all whom it may concern:

Be it known that I, KNUT LUDwIe STEN- nAnL, a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented a new and useful Cold-Blast Lantern, of which the following is a specification.

This invention relates to the class of lanterns known as cold blast lanterns'and has,

for its object to simplify, cheapen and to greatly improve the construction of the globe lifting and chimney lifting mechanism so'that the chimney ill be lifted entirely clear of the globe and the latter may be swung aside.

With these and other objects in view I have devised the novel construction of which the following description in connection with the accompanying drawings is a specific/a tion, reference characters being used to designate the several parts. 1

Figure l is an elevation of my-novel lantern, the dome and chimney being partly broken away to illustrate the chimney lifting mechanism; Fig. 2a section on the line 22 in Fig. 1 looking down; Fig. 3 an elevation showing the globe and chimney raised and the globe partly swung aside; andrFig. 1 is a section on the line 44 inFig. 3- looking down.

10 denotes the font, 11 and 12 the side side tubes, 14 the chimney, 15 the canopy which is carried b T the chimney, 16 the globe, 17 the rest by which the globe was carried and 18 the burner- I My novel globe and chimney lifting inechanism comprises essentially a shaft 19 which is j ournaled in the side tubes near their lower ends and is provided at one'end with an operating lever indicated by 2O.v The mid length of the shaft is. deflected to form a crank arm 21 which is pivotally connected to the globe rest as by an eye 22 on the under side of the rest through which the crank arm slides.

23 denotes a lifting rod which extends from the globe rest and then upward parallel with side tube 11.

24 denotes guides on the side tube in which the lifting rod oscillates and slides freely. At the upper end of the lifting rod is a head 25 provided with a guide 26.

27 denotes globe guards attached to the g-lestg1 one of which is shown as attached to the ca I conuemsr LANTERN.

' a 28 denotes the chimney lifting rod which extends upward and inward under the dome and through a slot 29 in the chimney. The vertical portion of rod 28 slides in a guide 30 on side tube 11, passes through guide 26 on head 25 and is provided at its lower end with an enlargement 31 which lies between head 25 andguide 26 resting onthe head and retaining the chimney lifting rod against longi- .tudinal movement independently of lifting rod 23. The upper end of the chimney lifting rod is shaped to form a head 32 which passes through and engages a link 33, the outer end of which passes through slot 29 in the chimneyand engages a cross pin 34 in side tube 11, the inner end engaging a cross pin 35in the chimney. At the lower end of the chimney is'a' strengthening ring 36 made of wire and provided with depending loops 37 which serve as stopsto steady the globe and retain it in operative (position. The globe may be readily remove when swung aside as in Fig. 3, by springing guards 27 sufficiently to permit it to be lifted from the rest.

38 denotes a locking catch on side tube 12 which is adapted to be engaged by the operating lever to lock said lever in place and with it the globe rest, globe and chimney 1 when said parts are in their normal or opera- I tive position as in Fig. 1.

tubes, 13 the dome which is carried by the The operation is as follows: To raise the globe and chimney the operator disengages j the operating lever from catch 38 and swings f the lever downwardas in Fig. 3.

This oscillates the shaft and causes the crank arm to lift the rest and globe swinging them side- I wise, as clearly shown in Figs. 3 and 4. The

n ,ward movement of lifting rod 23 raises the c imney lifting rod and with it the chimney through the engagement of head 25 with en- 7 largement 31 and the engagement of head 32 on the chimney lifting rod with link 33 (see Figs. 1 and 3). It should be noted as an important feature of the present invention thatthe link is so positioned and so engaged by the-head on the chimney lifting rod that the chimney is raised slightly faster than the globe and above the globe so that the latter is free to swing laterally. This construction renders it unnecessary for the operator to touch the chimney in use under any conditions likely to arise. Backward movement of the o crating lever from the position shown in ig. 3 raises the rest,

and. the chimney, whereby the chiim' is raised above the globe when the lat is raised.

2. In a lantern, thecombination rth a globe rest having vertical and movement, a lifting rod carried the clay a shaft havin a crank arm en b a rest which is raised, lowered and SWU k, b oscillation of the shaft oi a chimney normally resting on the globe and a chnnney lifting rod engaging the chimney and er.- gaged by the lifting rod to raise the chimney above the globe when the latter is aisec- 3. in a lante n, the combination with a globe rest havng vertical and sn'i movement and a chimney having vertical movement, of a shaft having a crank arm engaging the globe rest with a sliding connection and connections intermediate the chimney and the globe rest whereby the chimney is raised above the globe to permit the latter to be swung aside and is lowered upon the latter When it is returned to its normal position.

e. In a lantern, the combination with a globe rest having vertical and swinging movement and a chimney, of a vertic-lly movable chimney lifting rod, a link intermediate said rod and the chimney, and vcr tically movable lifting rodconnected to the globe rest and engaging the chimney lilting rod.

5. In a lantern, the combination With side tubes and a vertically movable chimney, oi a chimney lilting red having longitudinal mov ement on a side tube, a link intermediate the chimney lilting re d and the chimney, a h'ltm rod upon which the chimney lilting red rests and which is connected to a side tube, a globe rest by which the lifting rod is carried and means for lilting the globe rest.

6. In a lantern, the combination with side tubes, and a vertically movable chimney, of a chimney lilting rod longitudinally movable on a side tube and connected to the chimney, a shaft journaled in the side tubes and hav ing a crank arm, a globe rest pivotally and slidably connected to the crank arm and a. lilting rod extending from the globe rest and engaging the chimney lilting rod.

7. in a lantern, the combination with a globe rest and a chimney, of a shalt having a crank arm pivotally and slidably connected to said rest, a lilting rod extending from the globe rest and having a head and :1. guide, and a chimney lilting rod which cuthe chimney, passes through the guide and is provided with an enlargement below the guide which is engaged by thrhead. wh reby the chinu'iey is raised abovc the when the latter is raised and uuug sidcivise by oscillation of the sl all.
